RAILROAD-CAR WHEEL.

Specification of Letters Patent No. 1,377, dated October 21, 1839.

To all whom it may concern Be it known that I, DAVID COOKLEY, of thecity of Lancaster and State of Pennsylvania, have invented a new anduseful Improvement in WVheels for Railroad-Cars, called the Single Plateand Bracket Wheel and I do hereby declare that the following is a fulland exact description.

The rim A and flange B are of the usual size and form, and the spacebetween the rim and the hub C is filled by a concavo convex plate D,extending from the front side of the rim to near the back end of thehub, the convex of which plate projects about one inch an eighth of aninch beyond a straight line with the back part of the rim. A smallfillet or astragal E fills up the acute corners both of the hub and rim.The front or concave side of this plate is supported by about tenbrackets F, extending from the hub along the plate about four fifths ofthe space between the hub and the rim. A double number of brackets Gextend from the rim at the flange about one third the distance towardthe hub on the back or convex side of the plate. The back part of thehub H project-s about two inches beyond the usual length of the hub,which two inches is bored out sufficiently to receive the axle or shaftat its full size freely, so

that in case the axle should break at the shoulder, it could notimmediately fall out of its place.

The advantage of this wheel over others is that its increasedconcave-convex form is sufficient to overcome all danger of its crackingby the shrinkage of the metal, and by means of the brackets strength isgiven to the wheel. In this casting no coring is necessary, save that ofthe hub. Therefore it has every chance of becoming a perfect and solidwheel, and is thought to possess a combination of strength, superior toany heretofore used.

No. l of the drawings shows a front view of the wheel; No. 2, a view ofthe back, and No. 3 exhibits a cross section.

hat I claim as my invention, and desire to secure by Letters Patent, is

The employment of brackets on the back or convex side to support therim, and also the additional length of the hub, with a bore sufiicientto receive the axle at its full size, as a safety in case of the axlebreaking at the shoulder, all as herein described.

DAVID OOCKLEY.
